<p>A sawing apparatus has a frame, a saw blade rotatable on the frame about a horizontal axis and displaceable transversely of the axis, and a conveyor for displacing an elongated workpiece longitudinally in a transport direction generally parallel to the saw-blade axis past the saw blade. The conveyor has upstream and downstream drive rollers flanking the blade mounted on the frame on one side of the workpiece and respective upstream and downstream holding rollers mounted on the frame transversely juxtaposed with the drive rollers and engaging the opposite longitudinal side of the workpiece. Upstream and downstream abutment blocks on the frame engageable with the one side of the workpiece immediately flank the blade and upstream and downstream pusher blocks on the frame engage the opposite longitudinal side of the workpiece transversely opposite the respective abutment blocks. Upstream and downstream measuring rollers on the frame transversely engage the workpiece immediately upstream and downstream from the blade and are associated with respective sensors that detect how much of the workpiece has passed the respective measuring rollers in contact therewith. Respective upstream and downstream biasing units on the frame urge the measuring rollers independently of each other transversely against the workpiece.</p> |
